Yep! Mau5 is a hardcore gamer at heart! All of his song titles and lyrics are based on weird stuff, take 'The Veldt' for example, its a pretty twisted book, google it! Yet Mau5 crafts this beautiful piece from it! http://www.youtube.com/watch?v=_esYONwdKuw
Also the video has the same art style as the xbox game 'Limbo'
